The key difference between g3 and sf6 gas is that g3 is a gas mixture while sf6 gas is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.Get price

g3 - GE Grid Solutions

Alternative For High Voltage Applications. SF 6 Sulfr hexafluoride (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 Sulfr hexafluoride is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.Get price

Toxic substances list: sulphur hexafluoride - Canada.ca

Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.Get price
